Application filed July 29, 1913. Serial No. 781,715.

To all whom it may concern Be it known that I, Paon'r BAXTER, a. subject of'the King of Great- Britain and Ireland, residing at 6- Tud'or street, London, England, have invented new and useful Improvements in Vaporizers for Petroleum or Similar Oils; of which the following is a specification.

This invention-relates to Vaporizers for dealing with mixtures of air and atomized petroleum or other similar oil and treating them by heatto'form substantially fixed gas for use as a fuel in internal combustion engines and has for its object the construction and arrangement of such a device whereby a supply of gas of uniform character under varying conditions can be obtained such as occur in the running of a motor car owing to the wide range through which the power has to cope with the ever changing I resistance to traction on the road.

} ing conditions and it is the When-the power factor issubstantially constant there is practically no diiiiculty in maintaining a supply of gas from petroleum. or similar 'oil to give an economical result but when the conditions vary as hereinbefore described special arrangements are nec-.

essary to insure a gdod uniform set of workpurpose of this invention to obtain uch. w

The invention consists in a special form of vaporizer in winch-a mixture of air and atomized petroleum or other similar oil is allowed to pass comparatively slowly through a number of heated passages of comparatively small cross sectional area so as. to thoroughly subdivide the mixture during the heating and subsequently to deliver the heated mixture into a reservoir maintained at a high temperature sothat the engine has always a considerable reserve supply of heated gas of a substantially fixed character to draw upon.

In order that the invention may be the better understood I will now proceed to describe the same in relation to the accompanying drawing reference being had to the letters and figures marked thereon.

Figure 1 1s a sectional elevation of a vaporizer constructed in accordance. with my IZIVGIIUOD. Fig. 2 is-a, transverse section of the same on the line 1--1 of Fig. l.

The vaporizer consists of a casing 11 preferably circular in shape and having detaohableends to each of which is connected the, exhaust pipe c, "at the internal combustion engine the direction of the exhaust gases bein as indicated by the arrows.

ithin the casing 02 and at the upper part thereof is arranged a tube e connected by a pipe" at with the usual 'carburet-ing device not shown, andat the lower art is another posed as td'break' up and absorb the heat from the exhaust gases on their passage through the casing the heating'of the mixture in the tubes taking place when the gases are thoroughly sub divided and traveling at ture reaches the reservoir 9 it'ismaintained therein at a high temperature and with a considerable reserve amount to insure uniform working conditions. The mixture is withdrawn from the reservoir by the suction of the engine through the induction pipe 71 in the usual way. It will beseen that bytreating the mixture inthe manner described it is thoroughly heated and rendered stable of condition before use.

Whatl claim is: A

A vaporizer fortreating a mixture of air and atomized petroleum or other similar oil for use as a fuel for internal combustion engines comprising in combination a casing, means for passing the exhaust products of combustion from engine through said casing, a supply conduit disposed in said casing and exposed to the exhaust products and con-. nected to the petroleum and air mixing device, a delivery conduit disposed within said casing in a position complementary to the said supply conduit, a series of conduits of relatively small cross sectional area transa comparatively slow rate. When the mix-.-

'verselydisposed between said supply and delivery, conduits to break up the stream of mixture into a number of streams of com- .pai'ativei of the exhaust gases to be absorbed thereby, and a reservoir of comparatively large volume within said casing connected with said supply conduit and disposed in the path of the hot 7 exhaust gases on their passage slow velocity and cause the heat -through the casing, substantially as de 10 scri d. V

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
